MAURICE HOFHEIMER, OF NEIV YORK, N. Y., ASSIGNOR OF ON E-I-IALF TO CHARLES M. BECKER, OF SAME PLACE.

STREET-SIGN.

SPECIFICATION forming part of Letters Patent No. 472,050, dated April 5, 1892. Application filed May 26, 1891- Serial No. 394,109- (llo model.)

To aZ Z whom it may concern.-

Be it known that I, MAURIoE HOFHEIMER,

residing at New York, in the county and State of New York, have invented an Improved Street-Sign, of which the following is aspecification, reference being had to the accompanying drawings, forming part hereof, wherein Figure l is a side elevation of a lamp-post carrying my improved street-sign, the sign being shown in section. Fig. 2 is a perspective View of the street-sign; Fig. 3, a top view of the same; Fig. 4, a detail cross-section, on an enlarged scale, of one wall of the streetsign; and Fig. 5 an enlarged top view of one of the corners.

The object of this invention is to supply lamp -postsmainly those having electric lights-with street-signs which shall be conveniently visible during the daytime, and" which shall also disclose the names of streets, &c., at night without blinding the eye of the observer.

The invention is applicable not only to lamp-posts, but also to other analogous purposes; and it consists, mainly, in combining a prismatic or cylindrical sign with an inner truncated pyramidal or conical reflector.

The invention also consists in other details of improvement that are hereinafter more fully specified.

In the accompanying drawings, the letter A represents a lamp-post carrying at its upper end the electric or other light B. At the proper distance below this light I attach to the post A by brackets or braces a a a truncated pyramidal reflector 0, whose reflecting-' surface inclines outward and downward, as shown in Figs. 1 and 2, and is adapted to receive from the lamp the rays of light, as indicated by the lines marked b in Fig. 1. Around this truncated pyramidal reflector C, I place in an upright position the street-sign D, which, as shown, is composed of four signboards having the lettering transparent and the remainder opaque, or vice versa. The collection of sign-boards D constitutes, as Fig. 2 discloses, a prism surrounding the truncated pyramidal reflector O. The rays of light striking the reflector will be deflected on the surface of the latter, so as to pass through the transparent portions of the signboards D, rendering the reading of the ineyes.

made pyramidal, as shown, may be made in form of a truncated cone, and the sign-board D, instead of being prismatic, may be cylindrical, the main point of invention being that the reflector shall be inclined toward a substantially vertical sign-board, so as to throw the rays of light through the sign-board.

The manner in which the combined reflector and sign-board is clamped to the post A or other support is plainly indicated in Fig. 3; but any other mode of attachment may be used. Whenever the lamp-body B is so located or constructed that its rays will not properly strike the reflector C an additional reflector E is placed above the lamp B, as shown in Fig. 1, for the purpose of throwing the rays down upon the reflector O, in manner indicated by the lines I).

" In order to prevent snow, rain-water, orthe like from collecting between the reflector C and the nearest sign-board D, I leave the lower edges of the two separated, so as to allow an outlet 0., asindicated in Fig. 4, through which all foreign matter will pass away.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. The truncated pyramidal or conical reflector 0, combined with the prismatic or cylindrical sign-board D, the greater diameter of said reflector being placed near the lower part of the inner side of said sign-board, substantially as herein shown and described.

. 2. The combination of the post A, carrying the light B, With the inclined reflector Oand uprightsign-board D, the greater diameter of said reflector being placed near the lower 7 end of the inner side of said sign-board and with the bracket a, substantially as herein shown and described.

3. The combination of the post A and its lamp B, with the upper reflector E and lower inclined reflector O, and substantially upright sign-board D, substantially as and for the purpose specified.
